There is no virus by this name. However, we occasionally get queries
about this file.
SUHDLOG.DAT is created to the root directory of drive C: during the
setup of Windows. It contains backup copies of the original boot
sectors of the machine and the system files. This file is not used by
Windows unless you uninstall it - in which case the boot sectors
and system files are restored.
If your machine was already infected by a boot virus before installing
Windows, the infected boot sectors will be copied to SUHDLOG.DAT.
After this, F-Secure anti-virus products will find a dropper
infection from this file. This is pretty harmless, and the best way to
correct this problem is to make an extra copy of the SUHDLOG.DAT to a
floppy disk which is stored in a safe place (an expert could fix the
file manually if you need it for uninstall purposes) and just delete
the SUHDLOG.DAT file from your hard drive.
On a related note, F-Secure Anti-Virus had a false alarm of the
Lamerman virus in this file on June 15th, 2001.
